BAKER GAUGE.

Application filed May 16,

This invention relates to a device for dressing saws, more particularlyto a gauge for use for olntmg downrakers in a raker tooth saw, but it isto be understood that a gauge, in accordance with this invention, can beemployed for any purposes for which it is found applicable, and theinvention has for its object, to provide in a manner as hereinafter setforth a raker gauge which is simple in its construction and arrangement,

strong, durable, compact, conveniently adjusted, thoroughly efficient inits use, read- 11y assembled, providing for accurate adjustment, andcomparatively inexpensive to manufacture.

From the foregoing and other objects in view the invention consists, ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1 is aside elevation of araker gauge, in accordance with this invention,

and further showing the adaptation thereof with respecttothe raker teethof a saw.

Figure 2 is an inverted plan of the raker gauge.

Figure 3 is a top plan view of the raker gauge.

Figure 4 is a cross sectional View thereof. Figure 5 is a perspectiveview illustrating the guide plate and adjustable carrier therew for.

Figure 6 is a longitudinal sectional view of the gauge.

Referrin to the drawings in detail 1 indicates abody portion ofpolygonal contour and which has formed integral with the top, at therear thereof, a head 2 which projects laterally, in both directions fromthe body portion 1. The front of the body portion 1 is formed with avertically disposed groove 5 which extends from the bot tom to the topof said body portion. The rear of the body portion 1 is provided with avertically disposed ovalshaped slot 6 which opens into the groove 5'. hThe hottom of the body portion 1, at the rear there- 1927. Serial No.191,774.

ofis formed with a vertically disposed openmg 7 having a threaded walland which communicates with the oval-shaped opening o'.

he laterally projecting portions 3, 4 of the head 2 terminate inoppositely extendmg arms 8, 9, of appropriate length and which projectabove the upper faces of the lateral portions 3, 4 of the head 2. Eachof said arms is formed with a pair of spaced vertically disposedopenings 10 having threaded walls. The inner ends of the arms 8, 9arepositioned in opposed relation from and are spaced from the forward partof the body portion 1. The upper face of the head 2 is formed with agroove 11 dis osed transversely thereof and the side wa s of the groove11 merge into the inner ends of the arms 8, 9. Adjustably mounted withinthe'groove 5 1s a vertically movable carrier 12 of a length greater thanthe height of the body portion 1 and which is formed approximately cen'trally thereof with a transverse opening13 having a threaded wall.Thecarrier 12 rides against the forward face of the head 2. The carrier12 conforms in shape to the contour of the groove 5. Mounted upon theupper end of the carrier and projecting forwardly as well as from eachside of the carrier 12 is a guide plate 13, of rectangular contour, andis formed in its forwardly projectin portion with a longitudinallyextending s 0t 14 arranged forwardly of, but in close proximity to thecarrier 12. In fact the rear side wall of the slot 14 is flush with theforward face of the carrier 12. See Figure 1. The slot 14 provides forthe passage ofthe raker teeth 15, of a saw 16. See Figure 1.

Extending through the slot 6 and threadedly engaging with the wall ofthe opening 13 is a clamping screw 17 for maintaining the carrier 12 inadjusted position. The head of the clamping screw17 abuts against therear face of the body portion 1 when in clamping position. Engaging withthe threaded wall of the opening 7 is a vertically disposed adjustingscrewf18 which provides means for vertically adjusting the clampingscrew 17 whereby the carrier 12 is adjusted with the screw 17 as it iscarried thereby. The plate 13 is secured to the top of the carrier 12,by a holdfast device 19 which has threaded engagement with 1 0 the upperend of the carrier 12 and further has its head countersunk in the plate13.

lrlounted upon the arms 8, 9 are stop man here 20, 21 for the saw teeth.The stop members 20, 21 are in the form of rectangular plates having thebody portions thereof of less thickness than the thickness of the bodyportions of the arms 8, 9., The stop members 20, 21 project forwardlyfrom the arms 8, 9 and are removably connected therewith by holdfastdevices 22, which extend through slots 23 formed at the rear side edgesof said stop members and engage the threaded walls of the openings 10.lhe stop members 20, 21 are of greater length than the length of thearms 8, 9, project from the inner ends thereof and overlap the guideplate 13.

The gauge is used for jointing down a ralrer or clearer tooth to theproper depth to suit the operator and can be used on any rakertooth sawwhere raker is not too large to go through the slot 1st in the guide orfiling plate 13. The stop members or plates 20, 21 bear on the groups ofteeth at each side of the plate 13. The plate 13 can be elevated orlowered by the screws 17 and 18. Screw 17 is a set screw and screw 18 isan adjusting screw. The plate 14 is secured to the carrier 12. If thecarrier with the plate 14 is to be lowered, screw 17 is loosened andscrew 18 lowered, this releases the carrier and the latter can bepressed down to suit the operator. If the carrier is to be raised, screw17 is loosened, and screw 18 turned in a direction to move upwardly tothe height desired, screw 17 is then tightened and the gauge is readyfor use.

It is thought the many advantages of a gauge, for the purpose set forth,owing to its simplicity and convenience in adjustment can be readilyunderstood, and although the preferred embodiment of the invention is asillustrated and described, yet it is to be understood. that changes inthe details of construction can be had which fall within the scope ofthe invention as claimed.
